摘要： Techniques pertaining to device and method for controlling an analog signal are disclosed. Using a single connection (e.g., a connector or a pin) without an external resistive element (e.g., a resistor), an analog output is digitally controlled and produced. According to one aspect of the present invention, a precisely controlled current is generated from a coded data that represents. A control unit is designed to control a working mode based on an input signal from the connection. In one embodiment, the working mode includes a default mode, a programmable mode, a testing mode and a shutdown mode. Under the programmable mode, a user determines a signal coupled in from the connection as desired, and a code unit codes the signal in accordance with a predefined protocol. The code unit then sends the coded data to a decode unit. The decode unit is designed to generate or control the current by the decoded data

摘要： A phase comparison of timing signals is made by combinational circuitry which receives the timing signals and a window signal, the window signal identifying edges of the timing signals to be compared. The comparison may result in a charge pumped output which can be fed back to control the phase of one of the timing signals. The phase comparator and charge pump circuit can be included in a multiplier circuitry in which the phase of an input signal is directly compared to the phase of an edge of the multiplied signal.
